I wrote my own class definition and placed it inside a file called mynewclass.rb. I then placed this file inside /usr/local/lib/ruby/1.8/mynewclass/. The mynewclass.rb file has require 'rubygems' require 'uuidtools' require 'xml_struct' inside of it. When I create a new ruby script and use require 'mynewclass/mynewclass' I get a load error from custom_require.rb saying there is no such file to load for uuidtools and xml_struct, however if I launch irb and do a require 'mynewclass/mynewclass' I can use the class just fine with no load errors. Is there a different method I should use to go about this the correct, and hopefully functional way? - Nathan

Dear Nathan, in what directory did you save the new script ? Assuming that it is saved as /home/nathan/new_script.rb, if you write require "mynewclass/mynewclass" into it, the error message you get is due to the fact that you don't have a /home/nathan/mynewclass subdirectory with a mynewclass.rb file in it. So you could give the full pathname, or save the mynewclass.rb script in the same directory as new_script.rb . Alternatively, you could set additional environment variables for ruby: http://www.rubycentral.com/book/rubyworld.html It sounds to me that you get this error because you expect Ruby to behave like Java ... right? If so, could you help me on a Ruby/Java problem for which I got no response so far ? http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/... Thank you very much! Best regards, Axel

The new_script.rb is saved in my home directory, however the mynewclass.rbfile is saved in the site_ruby directory that is recommended for placing end user created modules and extensions to ruby. I dont' have a problem with new_script.rb being able to load mynewclass.rb. The problem is that inside of mynewclass.rb it also requires a few ruby gems, and those ruby gems are what I am getting load errors for. The gems and mynewclass.rb are both in directories included in the default ruby load path, which is why I am quite confused at the errors generated. Sorry, I wish I could help, but I have never coded in Java! I have some limited knowledge of web apps implemented in Java and I believe you have to download the required libraries, place them in a lib directory, and then some how you should be able to create a configuration file that points to the libraries. Have only seen implementations for servlet and jsp code though, so I'm not sure how that all works with a normal Java application.
